2.9 Introduction of Modules
The design of STS Module, Power Module and Battery Module make maintenance and replacement quick and easy.
The modular and hot-swappable design of Power Module makes it a highly cost-effective solution to meet your
power requirement. The number of Power Modules installed in the UPS can be based on the initial needs. Once
the power requirement increases, you can easily install more Power Modules without interrupting the operation
of the system.
